culligan Medallist will not regenerate

I have a Culligan Medallist 8 With Soft Minder.
Everything was going along fine and we started noticing the water was no longer soft. I tried twice to regenerate manually but it doesn't work.
I have went thru the manual and the settings are correct.
The bypass valve is not in bypass.
The power supply is plugged in and it is full of salt.

Can someone give me some troubleshooting hints?
I am a mechanic and would like to give it a shot myself if possible..
thanks...gary

I have power to the unit, but when I hit the Regen button nothing at all happens.
There is a motor inside.
Once I hit regen, this should turn right?
I checked with a ammeter and there is no power coming from the contol board to the motor.
It says REG on the screen, if the motor was bad I would have a power at the motor leads right?
thanks....gary

Ok, here's what happened. I got it to start the regeneration cycle, but it would only put water out of the drain hose.I tasted this water and it is fresh, no brine. No water was entering the brine tank and even after removing outlet power from the control, the water continued to run out of the drain hose. I pulled the small line I believe fills/drains the brine tank and nothing came out. I had to bypass the softener to get the flow to stop from the drain hose.
There is maybe a foot of water in the brine tank at this time.

Sounds like the little connection of wires that are in the harness and hook on the board might had not a good connection and that you have it fixed.

Cycle of the Culligan be it older one or of of the newer ones..

Backwash
Brine Draw/Rinse
Brine Refill/Rapid Rinse.
The backwash is about 10 minutes then the brine draw/slow rinse for about 50 minutes followed by the brine tank refill til the float stops the fill and while that is going on it is doing a rapid rinse.

It will run strong or about 3 gpm for about 10 minutes and then slow down to about .5gpm for about 50 minutes, if the injector is working right and you undo the nut at that end of the 3/8 black tube and put our finger over the end it should pull the finger into the tube..
Then the next part of the cycle it will refill the brine tank and do a rapid rinse 3gpm at the same time, once the brine tank has its water it will stop that part(because of float) while conitnuing the rapid rinse for a few more minutes.
